Det har ju funnits lite frågor kring vilka fabrikat av tester som är bra.
Denna sida fick jag från ett inlägg som Defdac gjort, och tyckte det lät intressant, ni får dock göra er egen värdering av vad som är bra.
" De measurements sets of Sera are the most correct that I have tried. Especially the one for phosphate determination is very accurate. The sets of Dupla are also reliable (slightly less accurate than Sera), but often hard to read. The sets of Tetra are less accurate than the ones of Sera and Dupla. The sets of Velda are in my opinion so inaccurate that I would not advise to use them in the aquaristics.
Believe me, sometimes the differences are not acceptable anymore. I noted down differences of 20% and more. It goes without saying that such deviations, e.g. for phosphates, produce enormous differences in the results of the calculations (e.g. for the Redfield ratio)" "
